1 Kings 2:5

Thomson(i) 5 Now thou thyself knowest what Joab son of Saruia hath done to me; what he did to the two chiefs of the armies of Israel, to Abenner son of Ner, and to Amessai son of Jether. He indeed slew them, and shed the blood of war in peace, and stained, with guiltless blood, the girdle on his loins, and the shoes on his feet.
